Palpitations: Palpitations are an awareness of your heart beating, since most of the time we are not aware of our heart. This can be due to a fast heart rate, a slow heart rate, or an irregular heart rate. This can also happen in times of stress or anxiety. There really isn't a good way to diagnose it but they are usually benign if your heart is structurally normal. Would discuss with your primary physician.
